What's the best audio device that I can clip onto a pair of shorts when running and doing other multisport activities? Ceron Christchurch, New Zealand

Oh, Gauis Gear Guy (bet you haven't heard THAT one before), I have a multitudinous problem. I wrote to you years ago about detached toenails, and you delivered the goods shiningly. My problem is still with my feet. The last two trips I've taken in my Zberlans boots have left me hobbled, with huge Susan B. Anthony pus-bubbles on either heel. I went to a clinic and was informed that my feet were "problematic" and that I was wearing the wrong boot. My right foot while standing is about a quarter inch longer than the left. My feet are wide and low profile, with anemic arches and narrow heels. Oh yeah, I also have weak ankles. Now I have June trips planned in the Grand Canyon and the Sierra. I've bought the Superfeet shrink-to-your-dogs prosthetic insoles, but I need a new boot. What do you recommend, outside of foot-transplant surgery? Thanks, Thomas Perkins Alexandria, Virginia

I have a narrow foot (11B), and find most hiking boots are D-width or wider. Any suggestions for boots that come in narrow widths? John W. Stafurik Los Alos, New Mexico

I recently heard about a new water bottle for hikers that doesn't slosh. I can't remember who advertised it. It was a bottle with a baffle type device inside it. I called everywhere, and searched the Internet, but couldn't find it. Can you help? Dean Willis Boise, Idaho

Thanks to a little bicycling accident last fall—which resulted in four brain surgeries—I've decided to take up hiking. I'm considering a staff or trekking poles to help with my balance. I believe trekking poles would be overkill for me, and that a single staff would be fine, particularly since I'll be sticking pretty closely to trails. Do you agree, and if so, which staffs would you recommend? Roley Davidson, North Carolina

G'day Gear Guy, I off to Peru in June for some high altitude climbing and I love all my toes. I currently have Salomon Mountain Guide 8's leather boots. I not a fan of plastics and looking to see how I can upgrade the warmth of my Salomons. What would be your recommendation for gaiters/overboots? Would this be enough? Cheers, Greg Brisbane, Queensland, Australia

We have a cabin tent that leaks, mostly from the bottom corners and stake-out loops. I have sprayed the tent and sealed the ses, but it still leaks. Is there anything else I can do besides trash this store-brand tent? As for new tents, the Eureka Getaway 9 or Coleman Sasquatch both fit size-wise; I don't want to spend over $250, though. Lastly, why do air mattresses always deflate while you're sleeping? Do they have a low life expectancy? Sarah Granite City, Illinois

After a long hiatus (scared off by all the stories of cycling-induced impotence), I getting back into road biking. I own, and love, the all-purpose Leatherman Wave multi-tool, so would like to get a similar device for my bike; which, if any, do you recommend? Your acolyte in Albany. Steve Albany, New York

I have one of the new MSR MiniWorks EX water filters, my first, and it works great. One of my buddies tells me to filter water from a still pool, but another says to filter from fast-moving water: Do you think it matters much? Personally, I just try and go for the clearest water I can find. Mike Eldorado, Illinois

I'm fortunate enough to live a half-hour from Shenandoah National Park. Often I'll drive out there after work, park by the side of the road somewhere, walk into the woods, and sleep there for the night. My little travel alarm wakes me in the morning in time to get to work. If the weather is dry, I sleep under the stars, but I like to carry a light tent or tarp for sudden showers. So I looking for a one- or two-person tent that is: 1) Quick and easy to set up; 2) Weather-tight enough to keep me dry in a thunderstorm; 3) Moderately light; and 4) Fairly roomy. Any suggestions? Would a single-wall tent be a good choice? I've looked at the Integral Designs Siltarp too—would that accomplish my purposes? Bill Stell Charlottesville, Virginia

What sort of cookware will I need on two- to four-night backpacking trips in the Appalachian backcountry? Kenny Birmingham, Alabama

Are you sure about your advice (February 5, 2003) that it's OK to use the Coleman BlackCat heater in a tent? Coleman's Web site shows that one of their BlackCat models has electronic "ignition," so that no matches are required. It also says that it's safe to use them indoors "with proper ventilation." Maybe it would be worth calling someone at Coleman and asking their opinion. Michael Vancouver, British Columbia

In the piece on Sno-Seal you said, "I'm confident it's the only product to appear in both the 1943 and the 2003 REI catalogs." I wonder if that's true. I think it would be really cool to see a listing of the items that were in the first REI catalog that are still in the current one, and the price differences. Don Denver, Colorado

I considering purchasing a jacket and pants made of Gore-Tex Paclite that are on sale. Some of the garments I'm considering (Devil's Thumb Jacket and a Dabl Pants from The North Face) are no longer made with Paclite but are now made with Gore-Tex XCR. The jacket and pants are selling right now approximately 50 percent off, so they are a relatively good deal. Should I be wary of Paclite since TNF has stopped using it? Thanks for your advice. Jay Lenrow Baltimore, Maryland

After a few cold nights at high elevation I interested in investing in a 0-degree bag. My research has directed me towards a down bag, possibly with a Pertex or DryLoft shell. I have been considering the Feathered Friends Tern, but know little about the company. I've also looked into the Mountain Hardware Universe SL, but don't know the effectiveness of the shell. I would greatly appreciate your input. Carissa Colorado Springs, Colorado

Even with the netting on, my tent (The North Face's Roadrunner 2) gets really hot in the summer with the flysheet on. Could I just hang a tarpaulin above the tent and leave the fly at home? Wouldn't that provide good sun and rain protection, while also allowing for much greater ventilation? Grah Winnipeg, Manitoba

One quick question—how do I pick the right length for an ice axe? Thanks, you're the man! Paul Anacortes, Washington

What do you think of the Yashica T4 Zoom camera? In the past, you often recommended the now-discontinued non-zoom Yashica T4 Super; the T4 Zoom is advertised as its replacement. What is your verdict on the T4 Zoom? Worthy successor to the T4 Super, or an imposter with a trendy zoom lens that has unfairly appropriated the respected T4 moniker? Jock Washington, DC

What's a good bike light to buy for my boyfriend so that he can mountain bike at night? Something inexpensive but good quality, which will probably get used once or twice a week in good weather. Julie Boulder, Colorado

What's your opinion of the Trailstove wood burning stove for backpacking? Bill Stell Charlottesville, Virginia

Please help! I recently bought a new lead climbing rope (Bluewater Accelerator 60m 10.5 mm) and I did what I have always done: mark the middle with a Sharpie marker. Then the other day someone told me this significantly weakens the rope at the marking, enough in fact to cause the rope to break in a relatively mild fall. I wasn't sure about this, because I thought it only marked the sheath and didn't affect the core of the rope. Should I throw the rope out? I would rather not due to the expense, but I will if it's gonna cost me my life! Mike Pittsburgh, Pennsylvania

Everything I read about tents says not to cook in the vestibule, but then I read gear reviews that say it is large enough to cook in. What's the scoop-is it safe to cook inside your vestibule or not? Shaun Aleda, California

Hello Mr. Gear, I'm going to the Arctic National Wildlife Refuge late August/early September this year. Since the place is beyond the Arctic Circle and the timing is going to be late, I wonder if my insulating jacket—a Wild Things primaloft sweater—is going to be warm enough. Also, what's the difference between a three- and a four-season tent? We're trying to decide on a tent to take along, but I wonder if I should take a four-season tent. Last year we took a Sierra Designs Meteor Light to Alaska, but it really didn't perform under the gusty conditions. And this year, we're expecting very very windy conditions as well. Is there any three-season tents that can live up to gale force winds, or I'm just stuck w/ the dead weight of a four-season tent? Blanche Ingr Brisbane, Australia

I in urgent need of a warm sleeping bag for use on an upcoming desert running race I entered in, the Marathon des Sables in Morocco. Although this conjures up visions of heat and sleeping under wispy silk fabric whilst warm winds blow, the reality is that at night, temperatures can plummet to freezing. I'm not too concerned about cost and need a bag which is at least good for about 32 degrees, and most importantly, LIGHT!! It has to be carried and raced with for over seven days. Please recommend waterproof varieties or appropriate techniques as it can pour. Dio Wong Hong Kong, China

My summer bag is an Integral Designs Andromeda Strain (40-degree, Primaloft); my three-season sack is the North Face Cat's Meow (20-degree, Polarguard Delta). Both are sweet bags. My question: can these bags be combined (summer bag inside three-season bag) to make a winter bag? Will I gain much, or will the inside bag be unable to loft up and therefore not provide much additional benefit? Thanks! Bill Stell Charlottesville, Virginia

I was thinking about combining my expandable Mountain Hardwear Galaxy SL sleeping bag with the maker's 40-degree Down Upgrade bag. What do you think about combining these two sleeping bags for a Denali summit attempt? Rob Boston, Massachusetts

What are the best winter socks for snow skiing? When I ski, I rent boots and skis, but I find my feet always get cold. What socks should I get to make sure my feet stay warm? Should I use sock liners in addition to high quality wool socks? Brad Chapel Hill, North Carolina

Hailing from sunny California, this is my first year in college in Boston. Here's my situation: New England weather is windy, chilly, and often wet. I need a jacket that will get me through the winter but also look good around town. However, once I buy this jacket, I'll still need money to eat. What can you recommend that won't break the bank, i.e. as close to $100 as possible? Kyle Boston, Massachusetts

Not yet having gone digital, I have a standard 35mm camera with extra lenses, a detachable flash, and the requisite rolls of film and cleaning cloths. So, I'm looking for a backpack-style camera case with plenty separate compartments and padding. Ideally, it'll be sling-style, with small compartments on the front for ease in changing films, lenses, and so forth. I've already checked the local stores and a few large Internet sites, but they seem to make bags only for digital cameras now. Any suggestions? Sarah Tulsa, Oklahoma

For multi-day trips to the Sierras, I've been using an REI Wonderland external-fre pack, 5,000 cubic inches of cavernous, organized, old-school pack. Everybody I see these days, though, has internal-fre packs that look so comfortable (maybe they're fooling me). I still living in the '80s with my Wonderland? Is it time for an internal-fre pack? If so, any suggestions? Alex Chino Hills, California

I planning a two-day, one-night hiking trip along the Appalachian Trail and looking for a gear list. Could you suggest what to pack and a couple of menus (with per person measurements)? The last time I took a trip, my girlfriend and I lugged so much food we could have fed five. Seth New York City

My wife has been using a pair of Asolo AFS Ridge boots for our backpacking trips, typically extended ones through rugged terrain. The Asolos blew out a se in front of the laces and need to be replaced. We are considering the Montrail Moraines or the Asolo 520 GTX boots. Is the Moraine too much boot? Is the Asolo 520 enough boot? Any other suggestions? Louis Oregon City, Oregon

I'm hiking the Grand Canyon rim to rim this spring, and I'm wondering what footwear to use. I like the lightness and cushioning of the trail runners that I've been using for my ten-mile training hikes, but I'm wondering if I need something a little more burly for my unsteady legs over the course of the 24-mile hike. Any thoughts on the Lowa Tempest? Jay Phoenix, Arizona

I want to upgrade from a cheap pair of compact binoculars. Assuming I had a pile of money burning its way out of my pocket, would I see much difference between a pair of Nikon Travelites and Leica Trinovids? Also, are there any other models I should look at (through)? Joe Lawrenceville, Georgia

Much of my clothing made with high-performance fabrics, such as Coolmax, states that you should not use fabric softeners or dryer sheets. Why is that? If they are accidentally dried with a dryer sheet will they return to normal after the next wash or are the performance aspects ruined? Joe Helm Canal Winchester, Ohio

A couple years ago I bought a Condor tent from The North Face, being informed by the salesperson that it was a four-season tent, although I have since discovered that may not be the case. I planning a June mountaineering course in the North Cascades that requires a four-season tent. Will my TNF tent suffice? I haven't used it for a while and lost the instructions, so do you know how I can contact them? Russ Frostburg, Maryland

I do much of my hiking in northern California's poison oak-covered hills. Usually I can avoid getting oaked, but after a day of tromping through this toxic weed, just how long do its oils remain active on my boots, gaiters, and trekking poles? Has science determined a half-life for poison oak's poison? Carter Napa, California

I use a 1968 Pinarello road bike. So, I was on a nice ride when I heard this "boing" noise; before I knew it, the derailleur (I think it was the original) had tangled in the wheel. The derailleur is now in two pieces, so I need to replace it. Are there any brands or models you could recommend? Can I put new gears on such an old bike? Could this have been prevented? Anthony Green Bay, Wisconsin

I thinking of upgrading my steel fre road bike to a carbon fork. I have tried a carbon fork in the past, and found it to be somewhat unsteady at high-speed (40 plus mph) descents. I weigh 185 pounds-does weight have a lot to do with the choice of a fork? Any suggestions? Should I just save the money and stay with my tried-and-true steel fork? Steve Weinberger Spokane, Washington

I've been doing some research on altimeter watches and have come across a lot of bad reviews for watches that I thought were good. Which watch would you recommend between the Casio Triple Sensor Pathfinder, the Timex Helix Works, and the Suunto Vector (some guy told me the workmanship on this was terrible and it fell apart)? Nadav Jerusalem, Israel

Are there any one-person tents that you can combine to make into a two-person tent? Denise Centennial, Colorado

In search of the Golden Boot over the years, I've owned disappointing Danners, Limmer mid-weights that ate up my right heel, and a forgettable pair of Meridians. I have a fairly low-volume foot, and while my current boots—a pair of Vasque Sundowners (Gore-Tex old style)—work pretty well, my feet still get hot spots and ache after a 12-mile walk. What's the boot for me? Stephen Decatur, Alabama

I'd like to invest in a pair of waterproof-breathable pants for one- or two-week treks where I might encounter rain and snow. Ideally, the pants would not be too bulky as they might spend quite some time in my backpack (I hope). If possible, please note any brands that I can find in Europe! Nicolas Heverlee, Belgium

My Boy Scout troop is planning to buy some rappelling gear, but we need some advice first. Eric Shelbyville, Indiana

I'm looking for info on bike trailers, having checked out some B.O.B. models, the Yakima Big Tow, and Burley's Nomad. Any insights as to which one would be best for city commuting? Also, any suggestions for where I might look for a used one? Linda Olympia, Washington

I currently have an older version of the Tubbs Sierra snowshoes, but I find them to be too bulky and heavy for those trips where crampons are also required. How does the MSR Denali snowshoe compare to its competitors, and what is the "floatability" factor of the MSR snowshoes? It seems they're very narrow, so I'm curious if they will keep you from sinking in soft, deep snow. Scott Newmarket, New Hampshire

Will a pair of electric socks, worn inside waders, work when I'm steelhead fishing? More importantly, will these be safe if I'm wading in water? Ed Pawling, New York

I've got a Bibler Betid tarp, and looking for some extra protection for my Mountain Hardwear sleeping bag (down with Conduit SL shell). I don't want to carry the Betid's floor since it is a bit heavy, and doesn't offer the protection I want. Please suggest a sleeping bag cover or bivy that will allow my bag to breathe, yet shed any moisture from condensation or the occasional exposure to rain. I'd prefer not to break the bank on this, as well. Dennis Staley Englewood, Colorado

What are the alternatives to Gore-Tex? Are there any that stand out from a protection as well as breathability perspective? I would love a Gore-Tex shell, but cannot afford to drop $400 on one. Alex Charlotte, North Carolina

Do you know of any evidence that pepper spray is an effective defense against a mountain lion attack? Mike Rapid City, South Dakota

I have an aging Columbia anorak shell that I'd like to replace. The problem is that I'm having trouble finding any new anorak-style jackets. I don't mind pulling the thing over my head and love the big front pocket. Any suggestions for a replacement, something I can use when hiking, climbing, and skiing? Chris Albuquerque, New Mexico

Where can I buy a hip belt to use as a harness for pulling my homemade gear sled? Bruce Easton, Pennsylvania

Dear gear swi, I'm looking to get back into mountain biking but have absolutely no clue about mountain bikes these days. I haven't ridden one nor done any research in about six years. If you could reach into the vast knowledge that you call a brain and offer some advice on bikes in range of about $1000, I would be in great debt to you. (And I would prefer a hardtail.) J.R. Venice, California

I have a few trips planned in bug-infested territory. The problem is that I hate DEET. I just don't like using the stuff. And citronella-based products are useless. Is there anything new out there that is effective, safe to use, and won't melt plastic? Jake Santos Chicago, Illinois

In November I'll be doing the Hong Kong Trailwalker (www.trailwalker.org.hk), a 100-kilometer race with a lot of big ups and downs. I will probably do in about 25 hours. Last time I did it in Reebok DMX10's. I liked that they were lightweight and I think the cushioning helped my knees a lot on the downhills, but I developed large blisters and lost three toenails, which was rather unpleasant (I didn't get feeling back in one toe for six months.) I'm thinking that maybe the DMX's were just too flimsy for the trail and let my feet move inside them too much. What are your suggestions for other shoes to consider this time around? Mike Luechtefeld Dallas, Texas

After spending all my life camping in the mountains of the eastern United States, I've fallen in love with the southwest Texas desert, and I'm in the process of learning about those techniques and equipment that will work in that very different environment. No trees, blazing sun, the ground too hard to set stakes, fairly constant strong winds... The first problem to solve would be creating some shade... My Integral Designs Siltarp, which works great in the forests of Virginia, is useless as a sunshade, being almost transparent. Are there any tarps out there that would be suitable for sunshade duty, or is a piece of black six-mil poly my best bet? Bill Stell Charlottesville, VA

Any recommendations for a two-person backpacking tent big enough for a six-foot, five-inch, 250-pound camper? I already have a Sierra Designs Clip Flashlight two and it seems a bit small for just one person (me), especially after more than two nights of foul weather. Jim McGowan Charlotte, North Carolina

I'm planning on hiking Vermont's LT, and because of past knee problems I'm trying to pack as light as possible. I've been considering buying the Mountain Hardwear Phantom sleeping bag, but I'm concerned about its down fill. Any thoughts? How effective is the water-resistant coating used on the superlight bags? Neil Westport, Connecticut

I am looking for a tent that will repel dew, especially as I hate the damp feeling that comes from wet grass. Which tent do you recommend? I don't do much camping, but I do like to be comfortable when I do. Tara Bowler, Wisconsin

I'm planning a summit attempt on Mount Rainier this August and a possible bid for Denali in May 2004, so in the process of upgrading my gear, particularly boots and sleeping bag. My budget may not allow for separate gear for each climb. I've been looking at Millet's Everest Boot and the North Face Inferno bag as my options, but prices are steep! Do you have any other suggestions, and is this gear suitable, or even overkill, for both climbs? Michael Stoneh, Massachusetts

I want to buy some new cross-country skis that I can use for both touring and downhill, maybe something along the lines of the Karhu Catounts. While these seem to work well for touring on ungroomed trails, would these also suit for telemarking on blue-square trails? Rusty Cresco, Pennsylvania

Can you recommend a good cross-country skiing package that's suitable for both groomed trails and backcountry use? John Duluth, Minnesota

I looking for an internal fre pack that will handle solo weekends, and group week-long outings, but most importantly, comfortably fit my petite (105-pound), feminine fre without breaking the bank. What do you suggest? y Walsh Tallahassee, Florida

Recently a couple friends and I attempted a 14-mile backpacking trip alongside a Class II-III river, with 90 percent of our time spent boulder-hopping, the remaining 10 percent waterborne. Unfortunately, we only managed to go three miles before the small recreational rafts we had to transport our packs got ripped up by the rocks and all the bushwhacking. In light of this, do you know of any companies who sell floating backpacks? Or is there some kind of easy-to-pack inflatable for transporting gear through water. We'd like to complete the se trek next year, but need a better way to float our backpacks. Travis Roseville, California

I'm looking for a recommendation for hydration packs as Christmas gifts for my brother and his girlfriend. They live in the Bay Area and do a lot of outdoor activities such as trail biking, hiking, and climbing. Would you recommend the se model for each of them, or different ones? Verna Washington, DC

I have a bit of a problem. I must have put my pack away a little wet after a spring backcountry ski trip and now all the waterproof coating is coming off the inside of the pack. I have a siliconized nylon pack cover that I will probably use for an upcoming Sierra trip and sprayed the outside of the pack with Nikwax. I also always use a garbage bag inside of the pack to protect my gear. Do you think the pack is done and I need to bite the bullet and buy another? Or do you have any suggestions of ways to fix it? Tim Newport Beach, California

As a frequent trail runner, I looking for a backpack designed with running in mind. I would like something with ple storage for additional layers and supplies, certainly larger than a lumbar pack. Any suggestions? Connor Ann Arbor, Michigan

Your Gearness, I planning to drive cross-country this summer, hiking and camping wherever the road takes me. For the driving portion, I was thinking of investing in a GPS system to help with the "figuring-out-where-the-heck-I-am" moments. Do you have any advice as to the value of GPS for this? (I will not need it for hiking, using the old-fashioned technique of map, compass, and trail blazes) Realistically, I'd like to stay under $300, but will go higher for an exceptional device—one that does the navigating, driving, AND laundry. Charles New York City, New York

We're searching for a pair of sunglasses with a protective nose shield for a friend who has reoccurring skin cancer. Can you help us out? Tmy Tarentum, Pennsylvania

I'm going overseas for approximately two years. Unfortunately, there'll be no camping opportunities the whole time. Before finding out I was off, I purchased a new tent, sleeping bag, and backpack. What's the best way to store this gear so it's as good as new when I get back? Gil Beaumont, Texas

What do you know about the "Stealth Can" and its effectiveness? From what I read, it's impenetrable to bears and seals in odors to throw animals off the scent. I like the idea of pre-empting animals from entering cp, rather than "teasing" them with food they can smell but not reach. Mark Ewing, New Jersey

Will boiling or adding chlorine dioxide to water neutralize all organic chemicals (i.e., industrial waste)? Also, should you filter water after using iodine or chlorine dioxide to purify it? Does ViralStop (from SweetWater) kill anything other than viruses? Basically, what's the simplest, lightest way of neutralizing EVERYTHING? Seyil Toronto, Ontario

My sweetie and I are going to Everest's Khumbu Icefall this December, where it's likely to be numbingly cold. I'd like to buy her a toasty parka for this trip and have homed in on Feathered Friends' Icefall and MEC's Frobisher. But will those jackets be significantly warmer than our current 550-fill REI parkas? Should I pay for the 800-fill down or Nextec Epic (apparently the best thing since somebody figured out how to shear a sheep) if I go with Feathered Friends? Or should I be looking at other parkas? Robert Fairview, Oregon

I've noticed a strange paradox in my personality. When I go out to the woods, sitting in some remote beautiful locale I often in want of one thing: a margarita. I've often theorized different devices that I could construct to make a blender but nothing ever made sense. And then I found the GSI hand-cranking Vortex Blender. While I would never take this backpacking (OK, maybe on a day trip to be fancy in front of my exhausted friends) I would definitely be interested in it for kayak camping and car camping—so long as the ice lasts. But does the thing actually work? Or is this really a doomed fantasy of mine? I'm skeptical about the amount of effort this thing would take to crunch up ice. I'd love to pop this out and be a hero. Brian McCarthy Glendale, California

Long time reader, first time questioner: I have long been a fan of liquid-fuel stoves, but recently read your advice about the difficulty in obtaining white gas products abroad ["Do they sell white gas for stoves in Europe?"]. I about to head out on a nine-month round-the-world trip, so would like to take along a reliable canister stove. Do you have any information on which canister stoves will mate with the multitude of international propane canisters that I'm likely to find? Europe and Oceania are my probable destinations. Aaron Green Bay, Wisconsin

I'm interested in testing the triathlon "waters." Can you suggest any good bikes for a beginner triathlon biker, say, for under $1,000? Gary Quito, Ecuador

Do you have any tips for taking a dog on trail? I'm taking my dog on her first trip and want to protect my gear without constantly worrying about it. Are those packs dogs wear a good idea? Will she dage the inside of my tent? Kieran Hosey Frankfort, Kentucky

I'm looking for a pair of Gore-Tex mountaineering pants that I can use snowboarding in the Alps, climbing in rainy Scotland, or cross-country skiing in Norway—all without maxing out my credit card. Any suggestions? Jakob London, United Kingdom

I recently unpacked my tent to be hit by a powerful smell of chemicals and mold, so bad that it gives me headaches and I can't sleep in the tent. Could I just wash it with some mild soap to get rid of the stink? I believe that the ses were sprayed with some sort of leakproof sealant, so I think that's why it smells. Janie Kuala Lumpur, Malaysia

I have been contemplating hiking the Appalachian Trail. Having spoken to a number of through-hikers, I'm told that many are using homemade alcohol stoves made from soda cans. Can you give me your take on alcohol stoves? Have you had any dealings with an alcohol stove known as the Trangia? Mark New York City
